Application filed December 29, 1.913. Serial No. 809,225.

ventien, such as will enable others skilledl in the art to which it appertains-to make andi use the same.

rhis invention relates'to means fOr simultaneously adjusting the rolls of bean-picking machines and is adapted to thattype of f bean-picking machines in which a number' of pairs of rolls are arranged in an adjustable frame sideby-side and inclined dowin wardly, se that beans-fed tol the ripper' endl of each pair of rolls will travelldownthe channel formed between the rollsby the inwardly-moving peripherles thereof.

it has been found in practicethatina single crop of beans, those from diierent* localities require dierent adjustments of the distance between the peripheries-ofthe two rolls of each pair. Heretofore' it has been customary to adjust they rollscfeach pair independently, but since the adjustment must necessarily be very slight and since it' has been necessary for the operator to adjust each pair separately it has become customary to neglect the adjusting of the rolls to suit the different grades of beans and consequently a poorer separation and considerable waste of beans has been the result.

rThe object of my invention is to provide a quick and easy means for accurately adjusting all of the pairs of rolls of a set or battery simultaneously.

A further object of my invention is to provide a roll-adjusting means, whereby the required adjustment of the rolls may be accomplished without interfering with the raising or lowering of the rolls.

A still further object is to provide means whereby half of the rolls may be adjusted, both ends simultaneously, whether the rolls are in motion or stationary.

`With the above objects in view, the invention consists in certain new and novel features of construction, arrangements and combinations of parts, and the equivalents thereof, as will be more fully described hereinafter and pointed out in the claims.

Referring to the drawings:

Figure l is a view in perspective showing;

the general arrangement of the'rolls and means for revolving the rolls.

is a plan view showing a part of the frame, two batteries of rolls and their adjusting means.

Fig. 3 is an end elevation thereof, looking in the direction of the `arrow in Fig.r 2.

Fig. a is a sectional view, taken on line of Fig. 2.

Fig. 'is a detail of the eccentric pin.

Fig. 6A isA a sectional view taken onv liney Fig. 7 is a fragmentary viewin ci'osssec= tion of one set or battery of rolls-clearly showing how the outerrolls Vof each set are f adjusted. f

in tlie'dra'wings, l designates a suitable bean machine having a feed hopper 2.' 3 represents a suitable roll-supporting frame.

The-frame isadapted'to be placed atan ineline belowifthe-hopper.' The upper end of" the frame is suitably hinged to the machine `and the lower end is adapted to be supported by eliainsd, or their equivalentsy fonadj'ust ing thel frame to any desired inclination.

Rotatably mounted' in the adjustable rollsupporting frame are a plurality of resilient,

preferably rubber, rolls arranged :sets or batteries of one or more pairs to a set, pref-k nated 5, are non-adjustable and the other half,ldesignated 6, are movable or adjustable laterally. Each of the rolls of a set or battery is provided at its upper end with a pinion 7 meshing with the pinion of the next roll of the set.

The upper end of one of the rolls 5 of each set of rolls is provided with a bevelgear 8 adapted to mesh with a bevel-gear 9 mounted upon the drive-shaft 10, for imparting motion to the several rolls of a set. The rolls revolve in such a manner that the upper peripheries of the two rolls of each pair of a set travel toward one another.

Each of the non-adjustable rolls 5 is mounted at its ends in suitable bearings 11 secured to the upper and lower members of the roll-supporting frame.

I provide means for adjusting both ends of one roll of each pair.

Each of the adjustable rolls 6 is supported at its ends in movable bearings 12, pivoted at 13, to the upper and lower members of the rollssupporting frame respectively.

j A plurality of eccentric pins 14 are mounted adjacent the rollers 6 in the upper and lower members of the roll-supporting erablyin fours. Half oftheserolls, desigs frame. Each of the eccentric pins 14 is provided with an arm 15. The arms, secured to the eccentric pins mounted in the upper frame member extend in one direction, as downwardly and are pivotally connected at their ends with a link 16. The arms secured to the eccentric pins mounted in the lower frame extend in the opposite direction, as upwardly, and have their ends pivotally cenlnected to a link 17.

For imparting movement to the arms 15 for adjusting; the rolls 6, l provide a crankshaft 18. The opposite end of the Crankshaft is provided with a lever 19 having connection with the link 17. Moving the crank shaft moves the upper and lower ends of the adjustable rolls simultaneously.

I provide the lever 19 with a detent 2O adapted to engage a suitable quadrant 21 for the purpose of holding the rolls in any adjusted position. v

The smooth perfect beans roll or slide down the channel formed by the inner moving peripheries of each pair of rolls 5 and 6 and these beans drop off the lower ends of the rolls into a suitable hopper Q2. The rough or split beans and the stones, dirt and other foreign substances are squeezed between the rolls and drop into a hopper 23 arranged below.

Through the medium of the eccentric pins and the movable bearings, it will be observed that provide a roll-adjusting device, whereby the quick and easy adjustment of one of the rolls of each pair of a set or battery may be accomplished without interfering with the raising or lowering of the roll-supporting' frame.

It will also be observed that there is provided a quick and easy means for accurately adjusting all of the pairs of rolls of a set or battery simultaneously and in parallel relation to one another.

Having described my invention, what I claim and desire to secure by Letters Patent is:

The combination with the main frame of a bean machine., of an inclined roll-supporting frame, means for changing,` the inclination of said frame, of sets of rolls arranged in pairs, half of said rolls being adjustable and the other half non-adjustable, a gear mounted on one end of each roll adapted to mesh with the next roll of the set, means for imparting movement to one of the non-adjustable rolls of each set, an arm secured to each end of each adjustable roll. a camshaft, a link pivotally connecting the arms at the upper ends of the adjustable rolls, each of said arms being connected at one end to said camshaft, a link pivotally connected to each arm at the lower end of the adjustable frame, said link being pivotally connected at one end to an adjustable lever, which lever is connected at its lower end to said cam shaft. Y

In testimony whereof, l affix my signature in presence of two witnesses.
